What would cause a send email action to not trigger/log anything on a exit transition?

I've had issues in the past where when my send from email wasn't valid/active, it would just skip the send email action altogether. I'm sure there's lots of different possibilities down this rabbit hole though.

That's what I thought as first, but if I put a button to transition explicitly to the state it works just fine. Not sure why a entry during a transition wouldn't trigger it, but a button that flows through the stage directly to another would.

What is the trigger of your transition?

The old.total != total triggers a transition to notify which has an on entry transition to another state. If I put a button to go directly to notify for testing it'll send me the email.

FWIW - I had a workflow where it was checking Old Record : Total != Total and after I implemented SuiteTax it changed it to Old Record : Total != Tax Total, so I had to update it. Pretty sure anyways, it's possible it was always set that way, but I find that scenario unlikely.

@Christopher Quackenbush for your old total vs new total do you have a trigger of after submit also?

The transition is on before record submit. Does that change anything?

Yes it needs to be after submit to send an email
